Definitions

  • the present invention relates to threaded joints, in particular for connecting tubes of predefined length to make strings used in the hydrocarbon industry especially for use in the field of OCTG (Oil Country Tubular Goods) and in line pipes in offshore applications.
  • OCTG Ole Country Tubular Goods
  • Modern joints are generally designed with metal to metal seals made by the contact between two surfaces, positioned usually either at one end or at both ends of the threaded portion of the joint.
  • the two contact surfaces reciprocally interfere in the elastic range of the modulus of elasticity for an appropriate stress magnitude.
  • resilient seals are needed instead of or in combination with metallic seals to prevent penetration of external fluids in the interstices of the threads.
  • the joint seals resist penetration of the external fluids, or at least do not allow continuous exchange of the fluids already penetrated with the surrounding fluids, in order to reduce corrosion rate of the joint.
  • seals are usually pre-mounted onto the box, when making up the box the seal is dragged together with the box over the pin's threads. Due to the diametrical interferences needed between pin, box and seal dimensions for the seals to work properly, along with the geometric parameters of the connection such as thread profile, pitch, taper angle, stab angle, etc, the seals are inevitably forced to crawl over the pin's threads, causing damage to the lower surfaces of the seals or permanent deformations to the seal which would jeopardize the sealing efficiency during operation.
  • Seal rings having more complicated shape have also been proposed, e.g. rings with an "H" or "U”-shaped cross section to increase efficiency and prevent sea water from penetrating into the gaps of the joint.
  • seal rings are subject to such stresses and adverse environmental conditions, both during the initial make-up operation and during operational life, that their efficiency is much reduced after some time.
  • pre-mounting on the pin would be less harmful for the seal ring, some field applications require seal rings of simpler shape which must be pre-mounted onto the box.
  • US6550822 discloses a threaded joint including a water exclusion seal which is a pressure energized elastomeric seal positioned in a groove near each end of the joint to make a radial seal between the unthreaded area at each end of the joint and the unthreaded cylindrical area adjacent each end of the tubular section.
  • the shape of the ring section does not facilitate its dragging over the thread during make up. Because of this shape, the sharp corners hit the thread crests and are prone to get stuck in the thread. In case of joint break-out it becomes even more likely to damage the seal ring.
  • This joint uses standard seal rings available on the market. Therefore, the same ring design must be used under different connections, and does not make it easy to customise the ring geometry for each pin taper, stab angle, thread height and pitch, etc.
  • the cavity located between the lips fragilizes the housing, making it prone to rupture during break-out of the joint, when the lower part of the housing is dragged over the pin's threads, producing such a high deformation as to break it.
  • WO02068854 discloses a threaded joint having the features of the preamble of claim1. This joint uses only one elastomeric seal ring and one metallic seal ring.
  • the principal object of the present invention is to provide a joint having two innovative seal rings ensuring both a simple and reliable initial make-up and a high sealing efficiency during operation, particularly resistant to infiltrations of corrosive external fluids.
  • the joint according to the invention has two seal rings of novel design which ensure optimal sealability under particularly adverse operative conditions: the second or internal seal ring protects the threaded portions of the joint; the first or external seal ring protects in turn the second seal ring further improving the protection of the joint.
  • the solution according to the invention is more reliable in cases where no spare O-rings are available. Contrary to joints having seals of the prior art, like O-rings with circular cross section or similar, the joint according to the invention does not cause damage to the seal rings during break-out. This has the advantage that the same seal rings can be used for a successive make up operation.
  • Another advantage of the invention is to provide a threaded joint more reliable in real field operative conditions, where reliability is crucial and a reduction in operative costs in terms of time and tasks is desirable.
  • the first seal ring placed most externally to the joint has a cross section shape particularly suitable to be pushed like a wedge by the external fluid pressure deep into the space between the external lip of the box and the corresponding external surface of the pin, thereby improving the sealing capacity of the ring and consequently of the joint.
  • the fact of making the housing for the first seal ring in the internal surface of the box frustoconical in the portion coming into contact with the first ring, with its taper toward the inside of the box, further enhances contact of the first seal ring with the metal surfaces, improving sealing capacity. It also ensures that, starting from a limit pressure, the seal ring fully fits into the annular space between the lip of the box and the facing pin external wall.
  • a further advantage is provided by embedding in the body of the first seal ring a reinforcement ring, preferably made of metal and with a L-shaped cross section. This ensures a limited and controlled deformation of the first seal ring under action of the external fluid pressure.
  • the cross section of the first seal ring can also have a U-shape, this enabling the seal ring to become wedged in the frustoconical housing, so maintaining an optimal sealing capacity.
  • first seal ring is provided with an annular rib in correspondence with its edge, the external surface of the pin region housing said first seal ring before make-up being provided with a corresponding annular recess or step in order to stably house the rib.
  • the housing for the second seal ring placed internally to the joint, is configured to best match the shape of the second seal ring, and vice versa, whereby the second seal ring works synergistically with its housing both during and after make up.
  • Various cross section shapes for the second seal ring are provided which can be selected in dependence of the external fluid pressure acting on the joint.
  • a first embodiment of the second seal ring an improvement in the sealing capacity is achieved without increasing costs since the housing for the second seal ring in the joint according to the invention is easy to make and is not more complex or expensive to produce than the currently used groove configurations, which house standard O-rings of circular cross section.
  • the V-sectioned mouth ensures a better contact of the ring with the surfaces of pin and box when external fluid pressure is exerted on that end even in the annular space comprised between first and second seal rings.
  • the external protruding annular ribs either on one or both of the internal and external surfaces, ensure a better specific pressure on the surfaces of pin and box to which they adhere.
  • the seal ring internal surface ensures a good positioning and contact in the seal ring housing made on the pin external surface.
  • a reinforcement metal ring in the part of the body positioned more internally within the joint ensures that the second seal ring holds tight on the pin, creating a hoop tension.
  • the reinforcement ring is firmly fitted in the V-sectioned mouth and the seal ring is also provided with its own annular rib, in correspondence with an edge of a base, suitable during make-up to engage between the internal surface of the box, underneath a shoulder, and the external surface of the pin in order to further improve sealing.
  • the first seal ring in all its embodiments, is advantageously pre-mounted onto the pin, thus avoiding damage of this seal ring during make-up.
  • the second seal ring in its second and third embodiments it is also pre-mounted on the pin before make-up. Besides, in these cases, the second seal ring provides additional overlapped or redundant sealing functions, which secure tightness of the whole joint, even when one of the functions is itself overcome by the external fluid.
  • the second seal ring is instead pre-mounted in its housing on the internal wall of the box.
  • the second seal ring is retained in an annular housing by the inner surface of the box and the outer surface of the pin.
  • This annular housing can also be provided with a finishing and a coating layer.
  • the housing has a geometry especially designed to cooperate with the seal.
  • the joint of the invention needs only limited additional machining operations apart from the common threading operations.
  • a reinforcement ring preferably embedded in the sealing rings in their various shapes, prevents twisting of the ring, renders make up operation easier, and assures easier overall handling and make up of the seal ring itself.
  • a coating can be applied to the surfaces involved by the second seal ring for protecting the machined surface of the pin close to the vanishing thread region of the joint which is likely to be exposed to contact with corrosive external agents.
  • a threaded joint indicated overall by reference numeral 1, connecting two pipes together: a male pipe, commonly called pin 2, with a nominal external diameter D, and a female pipe also called box 3, with a nominal external diameter D1 equal to or greater than D.
  • the pin 2 has an external threaded portion 4 with male threads of appropriate profile, e.g. trapezoidal, the box 3 having an internal threaded portion 5 with female threads of profile complementary to that of the male threads.
  • the common axis of pin 2 and box 3 is indicated by A.
  • the box 3 ends with a nose 15.
  • the joint defines an inner space 16, containing the axis A of pin and box, in which the fluid, for example a hydrocarbon, such as natural gas or petroleum or other similar fluid, flows and an outer space 17 which can be in contact with fluids of various kinds such as sea water in some applications.
  • the fluid for example a hydrocarbon, such as natural gas or petroleum or other similar fluid
  • first seal ring 30 of elastomeric material.
  • the seal ring 30 has a frustoconical shape and its external surface 31 is tapered towards the internal part of the joint 1.
  • the external surface 31 of the seal ring 30 matches the internal surface 32 of the lip 33 of the box 3, which has also a complementary frustoconical shape, for an appropriate length.
  • This particular shape allows the seal ring 30 to slide along the pin 2 under the pressure exerted by the external fluid in operation, from its position at the moment of insertion until a final resting position determined by the magnitude of said pressure and by the capacity of the seal ring 30 to compress its overall volume by virtue of the counterpressure exerted by the quantity of fluid that remains trapped in the annular space 50 between the fist seal ring 30 and the second seal ring 6.
  • the seal ring 30 has a reinforcement ring 34 embedded in its body.
  • the reinforcement ring 34 has a cross section, viewed in projection on an axial plane, of L-shape with two arms 35, 36 perpendicular to each other.
  • the angle ⁇ of the L-shape can also be slightly larger or smaller than 90° and alternately the two arms 35, 36 can be of different length depending on the wrapping force that must be exerted on the pin 2, on the magnitude of the external fluid pressure that is exerted in the operative environment of the joint and on the final location that has to be reached by the ring after its initial sliding towards the internal part of the joint under action of the external fluid.
  • the reinforcement ring 34 is positioned as shown in figures 2 and 4 , i.e. with the arm 35 parallel to the axis of the seal ring 30 and the arm 36 perpendicular to the axis of said ring 30.

  • the arm 44 is embedded in the external arm 41 of the body of the seal ring 40 parallel to the joint axis A, whereas the arm 45 is embedded in the body of the seal ring 40 perpendicularly to the joint axis A.
  • the reinforcement ring in both embodiments of the first seal ring can be completely embedded in the seal ring or can have one of its surfaces exposed to the exterior of the seal ring, either flush to a base or protruding from this base.
  • the internal surface 37, 47 of the first seal ring 30, 40 has a frustoconical shape with a very slight taper, of an angle ⁇ lower than 10°.
